Slightly OT, does anyone have a good way to add manual function to a HV contactor? It would be nice to be able to turn on the DC/DC converter manually in case of 12V failure without having to rig a jumper. I vaguely remember that one of the OEM EV's had such a button in the glove compartment for that exact situation.
The simplest way is probably to add a manual switch to turn on the DC/DC. Just be sure it's DC rated for your pack voltage. Perhaps the simplest source of high voltage DC switches are antique 120/240v DC household switches. These are the ones that made a loud "clack" when you switched them on/off.
Or, add an Anderson connector to act as a switch. Plug in a mating Anderson that just has a shorting jumper.
